Title: Light control device
Inventor: KAWASHIMA HISAO
IPC: G02F1/313
Filed: 1989-12-28
Abstract: PURPOSE:To decrease the change in the coupling state of directional coupler before and after patterning by scattering the group films consisting of the same material as the material of control electrodes at specified intervals near these electrodes at the time of patterning. CONSTITUTION:Optical waveguides 2, 3 are formed on a lithium niobate crystal substrate 1 and a buffer layer 6 is formed thereon, on which the control electrodes 5 are provided. The spot groups 10 are formed of the same material as the material of the electrodes 5 simultaneously in the stage of forming the control electrodes 5. The spot groups 10 are formed by arranging the micro films of a square shape, one side of which is sized, for example, 10mum, at 10mum intervals and forming these films in the region apart 100mum from the control electrodes 5. As a result, the strains concentrated heretofore near the optical waveguides under the electrodes are dispersed and the change in the coupling state of the directional coupler 4 is suppressed.

Inventor: MURANAKA MASASHI
IPC: G01N1/00
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which a stuck organic substance can be identified and quantitatively determined with high accuracy by heating a region to be analyzed on the surface of a sample from its rear and collecting its desorbed gas to be analyzed. SOLUTION: A region to be analyzed and evaluated (a region to be analyzed) 2a on the surface of a wafer 2 is heated locally from its rear by a heating heater 3. A desorbed gas from the surface of the wafer 2 is analyzed, and an organic substance is analyzed locally. The desorbed gas from the wafer 2 is superposed on a carrier gas so to be passed through a collecting tube 5, it is collected by a desorbed-gas collection means 6, the organic substance in the desorbed gas is analyzed by a desorbed-gas analysis means 7, and it is identified and quantitatively determined. As the desorbed-gas analysis means 7, a GC/MS method is effective, but other method may be used. Thereby, the organic substance on the surface of the wafer 2 can be analyzed locally, and the distribution of the organic substance stuck to the surface of the wafer 2 can be evaluated.

Title: Image forming device
Inventor: NAKAE AKIO
IPC: G03G21/02
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of preventing an user from wastefully and erroneously copying a sheet by copying after obtaining the user's confirmation in the case of copying sheets exceeding the prescribed number. SOLUTION: The threshold as the number of sheets to be displayed on a screen for confirming the number of copied sheets is previously set, for example, 50. Then, the threshold is written in a nonvolatile RAM 25. The user intends to set 'nine' as the number of copied sheets by operating the ten key of a control part 11 before copying, but, the user erroneously depresses the 9-key twice, and then, 99 sheets are actually set as the number of copied sheets. In this case, an instruction that 99 sheets should be copied is transferred to a main control part 12.  The value of 99 sheets is compared with the previously set threshold of the number of copied sheets(50, in this case) by the main control part 12, and in the case the transferred value exceeds the threshold, a confirmation message is displayed on the screen so that the user can recognize that the screen is remarkably different from the normal one.

Title: Production of rotor integral with blade and repairing method for its blade
Inventor: REIMONDO MAIKERU UOOKAA
IPC: F01D25/28
Filed: 1989-12-27
Abstract: PURPOSE: To manufacture or repair integrally bladed rotors with efficiency and precision by forming a repairing blade with a collar along its periphery and near its joint face that abuts a stub. CONSTITUTION: An existing blade is removed except a stub 16 that projects from a disk face 14 as part of the existing blade and has a joint face where a repairing blade 18 is bonded. The repairing blade 18, which has a collar 30 formed near its joint face that abuts the stub 16 and along its periphery, is positioned in close proximity to the stub 16 via the collar 30, through which pressure is applied to these joint faces. These joint faces are softened until metal fusion or the joined portions are locally heated up to the temperature that causes bonding. The collar 30 is at last removed from the bonded repairing blade 18 by a machining process. The technique thus offers efficient and precise repairs of the integrally bladed rotor.

Filed: 1995-12-08
Abstract: PURPOSE: To produce an electroforming shell having many through-holes by mounting a soluble sheet having many projections on its surface onto a substrate surface and subjecting this sheet to metal plating, then dissolving away the sheet. CONSTITUTION: The sheet 14 consisting of soluble blanks, such as resins and metals, having the many projections 32 is affixed by an adhesive to the surface of a pattern 1 for the electroforming shell consisting of an epoxy resin, etc., and a conductive coating material layer 16 of copper lacquer, etc., is formed over the entire surface of the sheet 14. Next, nonconductive coating material layers 17 of vinyl chloride lacquer, etc., are formed on the front end parts of the projections 32, by which an electroforming pattern 18 is produced.  This electroforming pattern is immersed into an electrolytic plating bath where electrolytic plating is executed with the electroforming pattern 18 as a negative electrode and the metals, such as Ni and Cu, as a positive electrode to deposit metal plating layers 19 of Ni, Cu, etc., having a prescribed thickness T and to form the electroforming shell. The electroforming shell is thereafter taken out of the plating bath and the resin sheet 14 is dissolved away by an org. solvent or by heating. The electroforming shell 19 having the through-holes formed by dissolution of the projections 32 is parted from the pattern and is thus produced.

Title: Manufacture of liquid crystal display device
Inventor: YANA AKIHIDE
IPC: H01L21/84
Filed: 1993-12-22
Abstract: PURPOSE: To avoid the current effect of a transparent electrode and reduce the contact resistance of a source/drain by depositing a heavily doped semicon ductor layer and metal on the entire surface and selectively etching to form data lines and source electrodes connected to source regions. CONSTITUTION: After continuously depositing a heavily doped n-type polycrystalline Si 11 and metal 12 such as Al, a photosensitive film 13 is coated thereon, exposed and developed. When this film 13 is developed, the electrolyte of the developer liq. will lower along the Al bank but never contacts a transparent electrode 9 as the Si 11 acts as a barriers, thus preventing the current effect. The heavily doped n-type polycrystalline Si 11 directly contacts drain/ source regions 6a, 6b to facilitate the contact resistance control. The Si 11 and metal layer 12 are laminated to form a double structure which prevents the short-circuit.
